While promoting The Leftovers ahead of its premiere in 2014, series co-creators Damon Lindelof and Tom Perotta hit on one theme particularly hard: There would be no answers about the nature of the Departure, in which 2% of the world’s population disappeared without a trace. Much like the tortured characters, the audience would never learn where all those people went, nor what happened to them or why. It wasn’t hard to see this as a reaction to the infamously divisive finale of Lost — which was still getting Lindelof so much hate he left Twitter — but it was also a necessary scene setting.
